2009, discovery of a brand new phenotype for bacteria in slender nanofluidic slits; and to start with detection of local protein structures along DNA using strong-state nanopores
Our group studies bacterial mobile division which is aiming to constitute a ‘bottom up biology’ in artificial cells that could autonomously divide. Our principal interest lies in cell division, chromatin composition, and spatial Management.
Back again in 1991, Sumio Iijima in the NEC Corporation had noted the synthesis of carbon nanotubes. Band construction calculations advised that these nanotubes could exhibit metallic band conduction. This might be a major benefit above the conducting polymers we had explored, which were, actually, disordered semiconductors providing merely variable-assortment hopping conductivity.
Our get the job done was promptly adopted up by Many others, most notably by Phaedon Avouris and colleagues at IBM, who in Oct 1998 posted their conclusions on transistors comprised of one- and multi-walled carbon nanotubes in Used Physics Letters.
This yielded a breakthrough. In just just a few months, we were capable to measure transport through someone one-walled carbon nanotube. Determined by low-temperature experiments by an excellent PhD student in my group, Sander Tans (now a valued colleague and professor at Delft College of Engineering having an Energetic research lab at AMOLF in Amsterdam), we showed that carbon nanotubes were being genuine quantum wires with incredibly lengthy (micrometres) Digital coherence lengths — confirming theoretical predictions of metallic conduct.
Electrical transport in monolayers of phthalocyanine molecular wires and AFM imaging of one wire bridging two electrodes
‘At the beginning we looked at biological devices with a physical watch and acted on The premise from the equipment we realized. It took a number of years prior to we commenced Doing the job much more on the big biological difficulties. I then began to call it nanobiology, a term that did not exist at time.
2011, initially in vitro measurements of transportation across just one biomimetic nuclear pore complicated; improvement of multiplexed magnetic tweezers for kilo-molecule experiments; and resolved the system of homology recognition in cees dekker DNA homologous recombination
Imagine if, as opposed to using regular best-down silicon electronics, transistors could be designed from the bottom up working with single organic and natural molecules because the switching things? This idea, which grew to become the basis of nowadays’s field of molecular electronics, 1st emerged in the seventies.
But carbon nanotubes have remained a exploration matter of appreciable fascination to a lot of. Without a doubt, the outlook on making use of carbon nanotubes to construct useful gadgets, in locations such as radio-frequency electronics, electronic electronics and versatile electronics, stays vibrant.
Example (four) of bending configurations in 3D simulations of DNA rods on nanopores. A part of the membrane is proven in grey, the rim of your pore is highlighted in pink, and also a 3D rendering on the motion of the DNA rod is exhibited.
2001, discovery of solitary-electron transistors at place temperature based on nanotubes; realization of first logic circuits with carbon nanotube gadgets; and discovery from the molecular construction of DNA fix enzymes with AFM
Developments in nanotechnology within the 1990s created constructing electronic units from solitary molecules a likelihood. Cees Dekker recounts how his crew designed a place-temperature transistor based upon one carbon nanotube.
2004, discovery of recent physics in translocation of DNA by way of nanopores; initial experimental analyze of ions conduction in nanofluidic channels; 1st electrochemistry with personal one-wall carbon nanotubes; STM detection and control of phonons in carbon nanotubes; first electrical docking of microtubules on kinesin-coated nanostructures; initially biophysics characterization in the mechanical properties of double-stranded RNA; and initially single-molecule analyze of DNA translocation by a restriction-modification enzyme.
